Face value: sunscreen, lack of control group, and conflict-of-interest

A reader pointed out a 2016 paper published in Dermatologic Surgery.

Daily Use of a Facial Broad Spectrum Sunscreen Over One-Year Significantly Improves Clinical Evaluation of Photoaging – M. Randhawa et al. – Dermatologic Surgery: December 2016 – doi: 10.1097/DSS.0000000000000879

Duplications in Spectrum Plots

One of my recent investigations led me to expand my set of figure types to look at. For our 2016 mBio study, in which I scanned >20,000 papers for image duplication, I focused on real photos of Western blots, agarose gels, tissue sections, etc.

Some examples of photos from biomedical papers. Top left: Western blot. Top right: agarose gel. Bottom left: petridish with bacteria. Bottom right: immunostaining of tissue sections. None of these photos have image duplications. Source: Wikimedia Commons.

Concerns about a paper on HPV vaccination and pregnancy rates

A short post based on a Twitter thread I wrote today about a paper I had seen a while ago. You can also read the ThreadReaderApp post, which many people find easier to read.

A couple of weesk ago, I saw a social media post claiming that the HPV vaccine would cause infertility in women, based on results in a peer-reviewed paper. It sounded hard to believe, because many other studies have found that the HPV vaccine is safe to use. There was no time that day to look up the details and I let it go.

Weekly digest, July 23

Some interesting articles I came across in the past couple of weeks.

How a data detective exposed suspicious medical trials – David Adam – Nature
Anaesthetist John Carlisle has spotted problems in hundreds of research papers — and spurred a leading medical journal to change its practice.

‘Bad science’: Australian studies found to be unreliable, compromised – Liam Mannix – The Age
Hundreds of scientific research papers published by Australian scientists have been found to be unreliable or compromised, fuelling calls for a national science watchdog. For the first time, a team of science writers behind Retraction Watch has put together a database of compromised scientific research in Australia.

How to report misconduct to a journal

This post is based on a Twitter thread from April 2019, with some additional information. I have added some of my own reports and some UnSplash stock photos for illustrations.

I got several questions from other scientists who were interested learning how to report suspected misconduct or other irregularities in scientific papers. In this post, I will discuss how to do that.

Fabrication: The Diederik Stapel case

One of the most discussed case of fabricated data comes from the Netherlands. Diederik Stapel was a professor of Social Psychology at Tilburg University and the University of Groningen. Some of his research was featured on news sites, such as his Science paper that found that people discriminate more in messy environments or another (unpublished) study that thinking about meat made people less social.

PubPeer – a website to comment on scientific papers

If you are interested in scientific integrity, you will probably know PubPeer, a website where you can leave anonymous or signed comments on scientific papers.

PubPeer was launched in late 2012 by neuroscientist Brendon Stell and brothers Richard and George Smith, with Boris Barbour and Gabor Brasnjo acting as advisers. At the start, the founders and advisers were anonymous, but they revealed their identity in 2015.
